Question
Which of the following statements about transmission of nerve impulse is incorrect?
Options
Nerve impulse travels from dendritic end towards axonal end
At the dendritic end electrical impulses bring about the release of some chemicals which generate an electrical impulse at the axonal end of another neuron
The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a dendrite of another neuron
A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells
Solution
At the dendritic end electrical impulses bring about the release of some chemicals which generate an electrical impulse at the axonal end of another neuron
Explanation -
Axonal end contains vesicle filled with a chemical called "neurotransmitter" which cross the gap or synapse and generate electrical impulse at the dendrite of another neuron.
